UFS v2 - out of spec part #6 (collector core)

yup, that was the problem. The atty is now perfectly square and it's mouth is concentric with the top cap.

I've taken about 20 minutes to get it dialed in and it's performing like a champ! Great volume of vapor using a protected 18650 and a 1.5 ohm Cisco. Tasty, tasty!

Cool!

It will be a great backup then

Glad you got it sorted man!

Thanks for those very clear pictures. They are great for reference.

I would love to see some "After" shots at a future point but I guess that may not be for some time now you are enjoying vaping it so much!

My replacement collector core has arrived and I have found that the UFS is performing much better with it installed. Whereas before I would open the liquid control about 3 cm, with the replacement collector core I only have to open it about 5mm to get good feeding.


So, the conclusion is that the part was faulty and while my grinding did address the atty squareness issue, it did not leave enough clearance for correct juice flow to both atty breather holes.
